Vintage Minor Register

Any idea which if either of these starter pushes is correct for the 29 cammy minor i am restoring. And why did they copper plate the switches. Both innside and outside on the switch top was copper plated and just the inside of the lower half?

Hi Bruce,

I'm pretty sure the one on the right is correct for the early cars. Why everything is copper plated, presumably to aid conductivity, but seems like overkill!
